For the two front side vents and front and rear centre vents you need the following part numbers 8T0919177B, 8T0919177A, 8T0919178 (need two of these one for left and one for right vent). Paid £48 for these plus one repair wire which was £2.50 from audi. No looms for these so apart from the repair wire to go into the plug (just cut lengths of wire I had in the shed). Quite expensive for what your getting back but it annoys me not having lights there, its petty that was even part of the light pack. Not really been using the forum for a few years so not really sure who would be able to sell me parts on here.
Planning doing a write up once I'm done which hopefully will be next weekend so keep an eye out for some pictures
Thanks
